UPDATE: St. Louis police officer charged in wreck that killed 4

CLAYTON – A suburban St. Louis police officer has been charged with four counts of involuntary manslaughter-driving while intoxicated for a March accident that killed four people.

Charges were filed Tuesday against 41-year-old Christine Miller. She also was arrested Tuesday and unavailable for comment. It wasn't clear if she had an attorney.

St. Louis County Prosecutor Robert McCulloch said bond was set at $200,000, but because Miller is still recovering from severe head injuries suffered in the accident his office agreed to home confinement.

The accident on March 21 killed four people from India, three of whom were graduate students at Eastern Illinois Universty in Charleston.

Miller also faces a fifth charge tied to a fifth victim who was badly injured. She was a veteran officer with the Sunset Hills Police Department.
